SPECFICATION forming part of Letters Patent No. 302,045, dated July 15, 1884.

Application iiled November 1, 1881. (No model.) Patented in England September 30, 1081, No. 4,244; in Belgium October 31, 1881, No. 56,031; in France November 9, 1881, No. 145,156; in Germany March 10, 1883, No.`20,953, and in Austria-Hungary December 1G, 1883, No. 31,600 and No. 46,090.

bon vapors or spray, in combination with steam or without steam. i

The invention consists in a gasengine pro vided with two explosion-chambers which are united by atube, so that after .the explosion in one cylinder or chamber the burning gases will ignite, the gases in the other cylinder or chamber automatically. The gases used may be a mixture of air and coal-gas, or air andr hydrocarbon spray or vapor, which is formed by condensing air an petroleum orsome other hydrocarbon through tubes containing ,line Wire sieves or bunches of w1re.` l

The invention further consistsv in a perfo` rated metal ball arranged in the bottom of each Y cylinder, and connected with a water-pipe for condensing water into these balls, which Water isA converted into vsteam by coming in contact with the heated ball, this steam assisting in driving the engine. Y

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

I will first describe the double-cylinder engine shown in Figs. 1 to 14:, inclusive. This engine is constructed With vtwo Vertical cylinthe bearings of the. shaft D2'. The cylinders' A A and the tank E rest on a base, F, which is the foundation for the entire engine or machine, and contains the pipes and tubes for conducting the gases and vapors to the cylinders.

The tube c is secured in the walls of the cylinder A and of the tank E With perfectly Water-tight joints, and serves to conduct the iguiting-flame located at Xinto the cylinder A, to ignite the mixture of explosive gases. In4 the vertical open cylinderd, connected with the tube, a piston, b, fits, which is connected by a rod, c, With an eccentric-pin, d, on a disk, e, mounted on the shaft D2. y

The cylinder A is provided with a like small cylinder, f, in which a long piston, g, is moved up and down by a connectingrod, h, journaled on the eccentric-pintle c' of a cog-Wheel, lo,

`which engages With a smaller cog-Wheel, m,

rigidly mounted on the shaft D2. The pro- Fig. 13 is an end elevation Fig. 14 is a cross-sectional ele-- portion of the Wheel m to the wheel k is as one to two or three to four-that`is, the piston or plunger g makes one stroke for every two or more revolutions of the shaft D2.

The cylinder A is provided With a very narrow opening or slot, u, which is so located that it willonly be opened when the plunger B is at its highest position. In allits other positions the plunger closes the opening or slot a, which is connected by the pipe o with a like opening, p, of the cylinder A. This opening orslot p is located below the lowest point the plunger B reaches, so that this opening or slot can never be closed by theplunger. The pipe o is provided at its upper endthat is, at the end connected with the cylinder A with a valve-box, q, closed by a plug, r, as seen in Figs. 13 and 14, and containing avalve, q', opening from the cylinder, and pressed on its seat by a spring, r', or held'on its seat by its own weight. The gases of explosion of the cylinder A pass off through the opening s, which is only opened by the plunger B when this plunger is in its highest possible position. (See Figs. 1 and 4.) From this opening the waste gases pass into a pipe, r".

rl`he petroleum-vapor or other hydrocarbon vapor is obtained in the following manner: The petroleum is filled into the metal vessel u, and fiows through the pipe y into the pipe XV, which terminates in the channels H H in the base-plate F. The ball Z, provided with numerous pcrforations, permits air to enter and to mix with the petroleum-vapor in the tube XV, thereby forming an explosive mixture, so that the petroleum or other hydrocarbon will be very finely' divided. The knee-pieces or elbows J are provided with or contain a number of fine sieves, Z1, Fig. 10, which cause the petroleum to be distributed or spread on a very large surface. If desired, the knees or elbows J may be completely filled with sieves b2, or with twisted and knotted fine wire, all for the purpose of forming most minute particles of petroleum-that is, petroleum vapor or spray. The knees or elbows J are each provided at their inner ends with a valve, c, which is held in a closed position by its own weight or by a spring, (ZY, for the purpose of preventing a back-pressure by the gases of explosion.

For the purpose of carrying off all gases of explosion that might accidentally escape at the small cylinders a and f, these cylinders can be provided with a waste-gas tube, c; but 1n most cases these will not be required.

The operation is as follows: If the several parts of the engine are in the position shown in Fig. 1, and if the space in the cylinder A, under the piston B, is filled with a mixture of gas and air, or petroleum-vapor and air, the igniting-iiamc (at X) will pass through the tube c and ignite the mixture of gases in the cylinder A, causing an explosion. The opening through which the igniting-iame passes into the cylinder A is immediately closed bythe piston I). Vhen the plunger B has arrived at its highest position, the flame passes through the opening orslot n, passes the valvebox q, and, passing through the pipe o and the opening p, ignites the gases in the cylinder A, causing an explosion. Vhen the plunger B has reached its highest position, the gases of explosion pass off through the opening s and the pipe r, and so on. To start the engine, the fly-wheel is rotated several times, so that the plungers B B will create a vacuum, and will draw the mixture of explosive gases into the cylinders. The gas in the cylinder A explodes first, the shaft D2 makes half a revolution, and then the gases in the cylinder A explode. It is evident that the explosions can only take place after every second, respectively, third, or fourth revolution ol' the shaft D2, as otherwise there would not be sufficient time for the cylinders to be filled with explosive gases. The plunger or pistou r/ is so arranged in relation to the shaft D2 that it will make but one stroke to every two or three revolutions of the shaft D?. The explosive gases will thus be compressed by the descending plungers B B, for the piston or plunger g keeps the side opening closed, and at the same time prevents the fresh explosive gases that enter the cylinders from being forced out again. The compressed gases explode v with much greater power than liberated gases, and the remaining gases or products of explosion will be forced out through the small openings which the pistons b and g form (at the ends of the pipes leading from the cylinders) during their strokes.

In Figs. 15 and 16 a horizontal machine or engine is shown, constructed on the principle described above; but instead of using two cylinders I have one double-acting cylinder. The cylinder A3 is made of cast-iron and surrounded by a shell, B, in which the water for cooling it circulates. The cooling-water enters through the pipe C, and passes off through the pipe C. The petroleum (or other hydrocarbon) is filled into the vessel D, and flows through the cock cL into the tube d", which is provided with numerous fine perforations, and is contained in a larger tube, e, connected by the pipes f t g with the ends of the cylinder Ai. These pipes f g1 contain a number of Very fine wire sieves, i", which subdivide the petroleum, and mix it with the air entering through perforations in the ball Z. To prevent the back-pressure of the explosion, Ihave provided the check-valves n4 o". A pipe, p, with a valve, q, unites the two explosion-chambers of the cylinder A in such a manner that the exploding gases can pass 'from one chamber to the other and ignite the gases in the second chamber.

On the cylinder A there are two smaller cylinders, s4 t, containing the plungers or pistons u4 1"", connected by the connecting-rods w o* with the eccentric-pintles x" y", respectively. The pintle at* is on a cog-wheel, "1, rigidly mounted on the main crank-shaft V, and engaging with a cog-wheel, z, on which the pintle y* is fastened. The proportion of the wheel with the two-cylinder machine.

The gases in the lefthand chamber can be ignited by a flame arranged at m6, at which point there is an opening in the cylinder A3. rIhe plunger S5 is provided with an opening, y, and when the openings m and ys coincide the flame passes through them and ignites the gases.
